Title: Manufacture of waveguide made of mg alloy
Inventor: MATSUSHITA TOMIHARU
IPC: H01P11/00
Filed: 1985-06-06
Abstract: PURPOSE:To manufacture a waveguide made of Mg alloy with excellent surface coarseness and dimension accuracy without caring for fire by forming a through hole to the center of a raw material made of an Mg alloy with hot extrusion and forming the waveguide into a required shape by discharge processing. CONSTITUTION:A hot hydrostatic pressure extrusion is applied while placing a pressure spacer between a raw material 4 and a container 10 and between the raw material 4 and a mandrell 6 at 230-300 deg.C to form a hollow extruded rod 2 with 40phiX100. Wire-cut discharge processing is applied to the hollow extruded rod by using an Nc wire-cut discharge processing machine to form a waveguide. Since the center of the hollow extruded rod is hollow, the wire-cut discharge processing is applied very easily.

Title: Semiconductor integrated circuit device
Inventor: NEMOTO MORIO
IPC: H01L21/60
Filed: 1984-06-15
Abstract: PURPOSE:To prevent the failures caused by contact among bonding wires and to enable a crossing wiring and a tightly-contact wiring by using the bonding wires which are insulation-coated. CONSTITUTION:The bonding wire 5 which is insulation-coated 4 contacts an electrode 2, 2' on semiconductor chip 1, 1' to an electrode 6 of container. The bonding wire 5 insulated, for example, with a resin coating 4 is used to connected the chip 1, 1' of an integrated circuit device to the base ribbon 6. As a result, even if the bonding wires 5 come in contact with one another because of crossing of the wires or the tightly-contact wiring in which the electrode pads 2' are composed into two rows on the chip 1' in order to obtain much more electrode pads 2' and intervals among the bonding wires 5 are extremely narrow, the resin coating 4 ensures insulation among the wires and function of the wires are not lost.

Title: Production of superconducting cavity
Inventor: OKUDA MASAHIKO
IPC: C23C14/34
Filed: 1990-05-14
Abstract: PURPOSE:To improve the adhesion of a cavity main body to a thin film without decreasing the purity of the thin film at the time of producing the cavity having a superconducting thin film by sputtering by preheating the main body to a specified temp. CONSTITUTION:The cavity main body 28 consisting of a heat-conductive material such as a copper alloy is placed in a vacuum vessel 32, the vessel 32 is evacuated, and the main body 28 is preheated at that pressure. The heating temp. is preferably controlled to the saturation temp. (about 100 deg.C) of water at the pressure where the mechanical strength of the main body 28 is not decreased. The impurities such as moisture and. adsorbed on the inner surface of the main body 28 are removed by the preheating, and the inner surface is cleaned. Consequently, the adhesion of the main body 28 to the superconducting thin film is enhanced without increasing the pressure in sputtering, namely without decreasing the purity of the thin film, and the superconductivity is improved.

Title: Cleaning device
Inventor: TARUMATSU KATSUMI
IPC: G03G21/10
Filed: 1984-06-18
Abstract: PURPOSE:To obtain a satisfactory cleaning function over a long period by constituting a blade in such a manner that the friction effect thereof has the tendency to balance always on both sides of a revolving shaft for equalization so that the always uniform blade pressure can be exerted to an image carrying body in the transverse direction thereof. CONSTITUTION:The cleaning blade 1 having an equalizing function of a cleaning device consisting of the blade 1 which is brought into press contact with the surface of a traveling photosensitive body is so constituted as to have a sharp angle theta with the plane in contact with the image carrying body in the contact position of the edge of the cleaning blade with the image carrying body. The cleaning blade consisting of an elastic material such as urethane rubber is used as a cleaning means and is applied to a copying machine in which a rotating cylindrical photosensitive body is used. Then the torque acts to eliminate the unbalance in the friction between the cleaning blade and the image carrying body even if such unbalance arises. The function of maintaining uniformly the blade edge in contact with the surface of the image carrying body at all times is thus obtd.

Filed: 1989-05-17
Abstract: PURPOSE:To prevent a cutting unit form rapidly falling down by simple configuration by forming an elastic part, which elastically contacts with a supporting part and lowers the moving speed of the cutting unit from an upper position to a lower position, between the upper and lower positions, where the cutting unit is supported, in a pedestal. CONSTITUTION:When a cooker is not used, a cutter stand 4 is rotated at 90 deg. to a pillar 1b from a state that a notch 7 of the cutter stand 4 is engaged with a projecting part 2 of the pillar 1b. Then a groove 8 of the cutter stand 4 is made coincident with the projecting part 2 of the pillar 16 and the cutter stand 4 is moved to the lower end of the pillar 1b. Afterwards, the cutter stand 4 is rotated at 90 deg. again and returned to an original position. In such a state, a whole height can be lowered and a housing space can be decreased. Even in case the cutter stand 4 erroneously falls off when the cutter stand 4 is moved downward, a projection 3 is elastically slided in contact with the groove 8 and the falling speed of the cutting unit 4 is lowered. Then the rapid fall is blocked and damage for the cutting unit or fingers can be prevented.
